Abstract
A hydraulic tensioner (), comprising: abase (); a piston () mounted for sliding motion relative to the base (), the base () and the piston () defining a pressure space () therebetween and being arranged to be urged apart along an axis () upon introduction of a fluid into the pressure space (), the tensioner () having an internal bore () along the axis () having first and second ends along the axis and comprising a threaded component having an internally threaded portion () at the first end and coupled to the piston (); the tensioner () further comprising: a threaded stud () having an exterior thread which engages the internally threaded portion () of the threaded component; and a drive mechanism () arranged to transmit rotational motion from the second end of the internal bore () to the threaded stud; the tensioner being arranged such that rotational motion applied to the drive mechanism () at the second end causes rotation of the stud () relative to the threaded component, with the engagement of the exterior thread of the stud () and the internal thread of the threaded component causing the stud to move along the axis as it rotates.
